Research Interests

Ribeiro Pereira Group is focused on preclinical research using multi-imaging modality that aims at modulating the availability of surface targets by elucidating their regulatory mechanisms to enhance antibody- and non-antibody-based tumor therapies. The Ribeiro Pereira Group has four major goals:

  • Use biomolecules, ranging from small molecules to full-length antibodies, as tumor-targeting agents to deliver imaging or cytotoxic cargo
  • Use multimodal imaging to monitor the binding of molecular-targeted compounds to tumors before and during therapy
  • Use acute and temporal pharmacologic approaches to modulate tumor biology in ways that enhance tumor binding of antibody- and non-antibody-based cancer therapies
  • Improve cancer diagnosis and treatment by combining basic tumor biology with preclinical knowledge and clinical needs
